I struggled with folds in an earlier post, EDM #185--Draw a Cat. So, I sat down with my sketchbook and a very soft (8B) graphic pencil and really looked at some curtains. The top sketch is more life-like and the bottom sketch was more play, but I see some real improvement. I am still struggling to translate this into pen and ink. But, I see progress and that's what is important to me right now.
